Write a program that will read from a file and display to the console all the words in the file in alphabetical order along with the number of times each word appeared in the file. For example, if the input file is:

This is an example, of an input file for project four, as an example.

The output to the console would be:

an $3$

example $2$

file $1$

for $1$

four $-1$

input $1$

is $1$

of $1$

project $1$

This $-1$

To get the individual words from each line of the file use a regular expression $($perhaps with the split method of class String$)$ as shown in lecture. Note that the input file may contain reasonable punctuation marks separating the words.

Use a TreeMap to store the words and their counts $($that is$,$ TreeMap $)$ You will need to use the wrapper class Integer to hold the count of the words as TreeMaps do not store primitives. Allow the user to select the input file using a JFileChooser.
